This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve covering a stainless steel shaft. The dry shaft design prevents circulating fluid from contacting the shaft, supporting a 125 PSI operating limit. The mechanical seal assembly incorporates a ceramic seat and EPT rubber to accommodate fluid circulation. Pressure tappings on the suction and discharge connections allow for system monitoring.
The assembly utilizes a 15 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.46. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
